A low histamine diet is a type of dietary restriction that involves limiting the intake of foods that are high in histamine or that can trigger the release of histamine in the body. Histamine is a chemical substance that is involved in the body’s immune and inflammatory responses, and high levels of histamine can lead to symptoms such as itching, hives, flushing, stomach cramps, and headaches, among others.

The goal of a low histamine diet is to reduce the symptoms associated with histamine intolerance or mast cell activation syndrome, which is a condition in which mast cells release excessive amounts of histamine and other immune-system chemicals. A low histamine diet typically involves avoiding foods that are high in histamine, such as fermented and aged foods (such as cheese, wine, and yogurt), cured meats, smoked fish, and certain fruits and vegetables (such as avocados, citrus fruits, and strawberries).

It is also important to limit the intake of foods that can trigger the release of histamine in the body, such as alcohol, chocolate, and certain food additives (such as food coloring and preservatives).

It is important to note that a low histamine diet should only be followed under the guidance of a healthcare professional, as it may not be appropriate for everyone and can result in nutrient deficiencies if not properly balanced. A healthcare professional can help you determine if a low histamine diet is appropriate for you and help you plan a balanced and nutritionally adequate diet that meets your specific needs.
